Utility needed to automatically cycle through multiple accounts on same MT4 terminal at timed intervals to do two tasks

Let's assume that I have 20 accounts from different brokers loaded up in my one MT4 instance and I want to be able to automatically cycle through them all at a timed intervals. 

I want an external (and/or internal) program (utility) developed that has the ability to conduct timed open and close of multiple MT4 accounts (from different brokers) within the same MT4 terminal, cycling through them every X minutes, in order to do two tasks:
Task1: activate each newly cycled account with AutoTrading enabled to run any private EAs for the cycle duration; and
Task2: save terminal history to the directory folder, perhaps with a custom EA.    

Variables for Task1: 
Variable: cycle-time = 5 minutes; // option to change to any amount of seconds, minutes or days
Variable: accounts = 1234, 12345, etc // different account numbers in which I want to cycle through, separated by commas

Variable (bool): SaveAccountHistory = true; // if set to true, then save Account History report in default folder
Variable (string): Report_(accountnumber).htm // custom title of terminal history report to save

The cycle process: 

1) login and run (with green AutoTrading enabled) the first MT4 account listed (ex: 1234) for cycle-time (in order to run any privat EA for whatever purpose) 

2) during cycle time, run a custom EA (you develop) that saves Account History report (terminal > Account History > Save as Report)

3) at the end of cycle-time, close account (1234) and open next account in sequence, repeating steps 1-3

I'm not sure if this task would need the development of an external program outside of MT4 to handle the closing and reopening of accounts; I'll let you figure out the solution.
